抄録

Many mathematical models which represent the height dependence characteristcs of mean wind speed and turbulence intensity in the neutral atmospheric boundary layer have been proposed and conventionally adopted in practical loading codes.Basic parameters in those models are closely related with the surface condition, then different values have been commonly assumed based on a few previous works conducted before 1970. However, the change of the surface condition, especially in urban, can be anticipated and many reliable measurement results in recent years differ from in the previous ones. And then, some reconsiderations of those mathematical models and parameters are inevitable and, consequently, will be useful for the rationale evaluation of wind loads.<BR>In this study, mathematical models and basic parameters such as power exponent, roughness length and atmospheric boundary layer depth etc, are carefully examined by using full-scale measurement results reported mainly after 1970, and compared with the values in previous proposals and loading codes, in oredr to propose a possible revision for parameters.
